a sli'dable fulcrum 23. To this part is pivoted a lever 24L having horizontal and ve1tical'hanclles25 and '26. The lower end of the lever 24 engages a peripheral slot in one end of the member 20. To this member QO'is, secured a ratchetQT engaged by a pawl 28. The. part 9.) carries a tubular extension 29' within which is atrip80. having a hook shaped end, the whole being] pressed outward by spring 81. I

A coil spring 32 surroundmg'shaitt 3 and seated in a socket 34 in the frame 1 normally- 20 although they may be disengaged by fwheel. This has'not been illustrated as I consider 'it merely a duplication of parts.

At the start of operations, the trip 80 may be movedtoengage the'roller 18 (as in Fig. 3) by. movement of theratchet 27 by means of handle 26.. After this, movementof the traction wheels-will operate the rolls automatically. 1 p

'Also' securedtothe frame 1 is a bloc 35 (Fig. 9) carrying tension rod 36' secured to roll 10. This rodis surrounded by a coil s ring 37 which tends to keep the seed cavities in the rolls up beneaththe hopper. Nuts 7-38 permits desired adjustment of the ten-- sion rod 36. It will thus beseen that the teedrolls are dumped by the'trip 30 and returned to-receiving position by. the spring I tension rod 36. 5 7

It will be seen that any multiple of hop pers and feed rolls be used by merely increasing the; number of units.

. lhave tound it advantageous to provide directly beneaththe teed rolls, a funnel 88 "having a fle ible conducting tube 39 whichdirects the seed or grain 1nto the furrow.

I have shown a shaft 4L0 mount-ed upon -frame 1, carrying depending links 410011- nectedto a disc and'harrow bar 42. This bar carries the plows 43 and-cover discs 44 to 'make and cover the furrow respectively. A harrowf iti is mounted uponeach bar -42 to' follow the cover discs 4 L- .The harrow-endof bet-r42 has a standard I 46, the. twoetandards being tied together by 1 tiered L7. This last named'pa-rt is provided with uprights 48 carrying springs 49. The

uprights pass through apertures in a condescribed Comprising a mounted upon wheels carried by the 'li'rame, ahopper for the distribution of material to be planted, andteed rolls beneath thehopnecting rod 50, pins 51 in the tops of up- 8 rights 48 preventing accidental withdrawal of the parts. 05 An operating lever torthe disc bar 42 is shown at 49 pivoted to the frame at 50. The lower end thereof is bifurcated. as at 51, eacharm of this end straddling the con' necting rod 50.. A spring tension rod. 52 is pivoted beneaththe frame 1 and passes through an; elongated slot in the base of the bifurcated end of the lever 49. A coil spring 5?).keeps thisend. of the lever under tension. At all times this rod will engage and move over roller 54:. j i 7 When it is-desiredto lift the plows and harrows out of the ground, the lever 49 is moved forward and held in any desired. po-; sition by means of the pawl and ratchet mechanism 52 and 53 respectively. Where it is desired to leave thefhopper aperture permanently open and the funnel unobstructed, the rolls may be rotated until I their flat sides coincide, the trip disconnect ed, and in this position, potatoes or the like maybe dropped directlyfthrough hopper feedrolls and funnel into the furrowwith-' out obstruction. I l v lVhere thought necessary any type of plows or Cultivators be attached to either the plow bar 42 or to another bar provided for the purpose the object being to makethe device as applicable as possible for many uses. p 9 7 t is to be noted that as. shown thec-ircumierence of the traction wheels will determine the distance between dumpings ot the feed rolls, butas stated above, the same result may be secured by increasing the SIZG: ice

of the wheels. and increasing thenumber oi trips on the wheel'axlen V I I claim: 7

1. An agricultural implementot the type per, with a shut off door slid-able beneaththe hopper bottom one of said teed' rolls having teeth to engage said door and movethe same. A f r 2. An agricultural implement of the type described. comprising a frame, an axle mounted upon wheels carried by the frame, a hopper fortho distribution of materialto beplanted, and feed rolls beneath the hopper, said rolls being carried on'shaft-s, with a tension mechanism attached to'the frame and one of, said shafts, regulating? the'120 amount'ot rotation said feed rolls may have. In testlmonywhereof, I affix my slgnature.
